    Black crappie

    3/10 · Weak

    Hourly activity

    0:006:0012:0018:0023:00
    Bite activity:highmediumlow

    The bite is weak — fish are sluggish. A thunderstorm is possible: activity rises before the front and drops after.

    Peak bite hours

    Best time — 07:00–08:00 (dawn bite) and 20:00–21:00 (dusk bite).

    Tactics

    Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.

    Lures

    The water's turning murky — go with bright, noisy lures: small jig or minnow bait.

    Gear

    Pack transitional-season clothing — mornings and evenings are chilly. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.

    Summary

    A slow day — go only if you really feel like it.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 53 °F — colder than the 57–75 °F comfort range for Black crappie: the fish conserves energy and takes more cautiously.

    Black crappie works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.

    Pressure is rising 0.27 inHg over the day — the bite usually settles down after a rise.

    One more input — the moon's feeding windows: within their hours the score sits higher than across the rest of the day. The window times are in the “Solunar feeding periods” card below.

    Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.

    The windows are set by the moon's transit and rise, and the forecast above already accounts for them: within these hours the bite score sits higher than across the rest of the day, while the day's overall level still comes from the catch-calibrated model.
